面包屑链接无法正常工作

标签: php function breadcrumbs

我有这段代码 -

function breadcrumbs($separator = ' » ', $home = 'Home') {
    $path = array_filter(explode('/', parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH)));
    $base = ($_SERVER['HTTPS'] ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . '/';
    $breadcrumbs = Array("<a href=\"$base\">$home</a>");
    foreach ($path AS $x => $crumb) {
        $title = ucwords(str_replace(Array('.php', '_', '-'), Array('', ' ', ' '), $crumb));
        $breadcrumbs[] = "<a href=\"$base$crumb\">$title</a>";  
    }
    return implode($separator, $breadcrumbs);
}

让我说我在页面网址:

http://www.mysite.com/forums/general/log-book

此函数将面包屑正确显示为Home » Forums » General » Log Book

然而,当我点击其中一个痕迹导航链接时,它只会回到基本网站网址结构 - 例如“常规”会回到http://www.mysite.com/general,当它实际应该转到

http://www.mysite.com/forums/general

你们怎么建议我去解决这个问题?

请改为尝试:

function breadcrumbs($separator = ' &raquo; ', $home = 'Home') {
    $path = array_filter(explode('/', parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH)));
    $base = ($_SERVER['HTTPS'] ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . '/';
    $breadcrumbs = Array("<a href=\"$base\">$home</a>");
    foreach ($path AS $x => $crumb) {
        $title = ucwords(str_replace(Array('.php', '_', '-'), Array('', ' ', ' '), $crumb));
        $breadcrumbs[] = "<a href=\"$base$crumb\">$title</a>";  
        $base = $base.$crumb.'/';
    }
    return implode($separator, $breadcrumbs);
}

请注意更改的行$base = $base.$crumb.'/';

鉴于您的$path数组如下:

array(
   'forums',
   'general',
   'log-book'
)

你可能会倒退:

while (NULL !== ($crumb = array_shift($path))) {
   $title = ucwords(str_replace(Array('.php', '_', '-'), Array('', ' ', ' '), $crumb));
   $url = implode('/', $path) . '/' . $crumb;
   $breadcrumbs[] = "<a href=\"$base$crumb\">$title</a>";
}

注1:不要依赖HTTP_HOST。请改用SERVER_NAME。前者可以使用HTTP请求的Host: ...字段伪造。
